Con statement

Question

I'd like to convert all 255 cell values of one raster with the values of a different overlapping second raster. Both input rasters are 4 band, 16 bit unsigned integer tiffs.  I'm using the following con statement:  Con("ras1.tif","ras1.tif","ras2.tif","VALUE<>255").  My output raster is 8 bit unsigned integer tiff.  How do I maintain a 16 bit unsigned integer tif as the output raster and retain the 4 bands?

Dan and Jayanta.

That was pretty much my Plan B.  Looks like I'm headed to the land of Model Builder and Python.  Thank you for your time submitting comments and suggestions.

As mentioned by Dan Patterson‌, you might need to clip the image.

Lets say you need area of interest of Raster1 and the pixel values of Raster 2.

1) First, reclassify Raster1 with a single (1) class Reclassify—Help | ArcGIS for Desktop

2) Use the reclassified raster to create a polygon (non-simplified output. Raster to Polygon—Conversion toolbox | ArcGIS for Desktop

3) Use the above polygon to clip Raster2 Clip—Data Management toolbox | ArcGIS for Desktop

Keep "Use Input Features for clipping Geometry" checked.

But don't check "Maintain Clipping Extent" (Else the values might get compromised due to resampling).

You should get the clipped Raster with all the available bands of Raster2.

I don't suppose 255 occurs at the same pixel locations in all bands either...otherwise it sounds like you want to either mask or clip the image.  Mosaic datasets might offer some capability, but I haven't looked in detail
